EPA07 Engines
wv dm 06.04.002
The EPA07 ATS varies according to engine manufacturer
and vehicle configuration, but the exhaust muffler is replaced by
an aftertreatment device (ATD). Inside the ATD, the exhaust first
passes over the diesel oxidation catalyst (DOC), then passes through
the diesel particulate filter (DPF), which traps soot particles. The
soot is burned to ash during a process called regeneration (regen).
